good lesson to NEVER use this pseudo-RAID interfaces and use gmirror 
instead.

not only you can make more complex RAID setup, get higher performance from 
gmirror and be always able to access data independently of "hardware" RAID 
onboard which is just normal controller.

Just don't use BIOS RAID ever.
